Problems solved by technology

According to the survey on the energy consumption of existing large public buildings across the country, it is found that there are many problems in the existing large public building air-conditioning systems: 1. There are generally problems of high energy consumption and low management level. The current air-conditioning systems in my country are basically Control methods such as variable water temperature and variable flow are adopted, but it is often impossible to fully guarantee the reasona

Embodiment

[0109] Embodiment: A low-cost adjustment method for an existing large-scale public building air-conditioning system, based on design and actual use, including three models of air-conditioning system operation diagnosis, building load estimation, and system optimization target calculation. Each model is proposed It is based on the analysis and summary of a large number of measured data on the air-conditioning systems of large public buildings such as administration, commerce, education and scientific research. Ground-source heat pumps are relatively common air-conditioning systems in public buildings, so this adjustment method is only for ground-source heat pump units. Not applicable to other types of units. The specific methods of model acquisition will be described below, including research methods and data processing methods, and then the input parameters required by the present invention and specific prediction methods will be introduced.

Abstract

The invention discloses a low-cost commissioning method for an existing large-scale public building air conditioner system, which is mainly used for commissioning of a ground source heat pumping unit.The low-cost commissioning method comprises the following steps of step (1), constructing an air conditioner set failure diagnosing model; step (2), constructing an air conditioner system load estimating model; and step (3), constructing an air conditioner system optimization model. The invention mainly aims to complete preliminary accommodation of a building air conditioner system in a short time through information as little as possible. According to the method, three models are respectively used for three stages of diagnosis, load pre-estimating and optimization target calculation on a thebuilding air conditioner system.

Description

technical field [0001] The invention belongs to the field of building energy system adjustment, in particular, it relates to the diagnosis of the energy consumption of an existing large-scale public building ground source heat pump unit, the calculation of the energy-saving potential and the proposal of an optimization scheme, especially to an existing large-scale public building air conditioner A low-cost tuning method for the system. Background technique [0002] Commissioning in the construction industry refers to the supervision and management of the whole process in the stages of design, construction, acceptance and operation and maintenance to ensure that the building can achieve safe and efficient operation and control in accordance with the design and user requirements, and avoid due to Design defects, construction quality and equipment operation problems affect the normal use of the building and even cause major system failures. The present invention is mainly aime...
